JOHNSON SAXOPHONE Filed Oct. 22, 1926 J 5 a MW w 5.Y. n 5 A Patented Nov. 12, 1929 UNITED STATES PATENT OFFICE ALFRED J.JOHNSON, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO YORK BAND IN- STRUMENTCOMPANY, OF GRAND RAPIDS, MICHIGAN SAXOPHONE Application filed October2-2, 1926. Serial No. 143,402.

This invention relates particularly to an improved key stop movement forsaxo-phones or similar instruments.

The object of the invention is to simplify 5 such structure and avoidthe necessity of the accurate fitting of the stop to the valve or padand at the same time have an effective stop that is neat in appearance.

I accomplish the objects by the means described in the followingspecification. The

invention is defined in the claim. A structure Which is a preferredembodiment is shown in the accompanying drawing, forming a part of thisapplication, in which:

Fig. 1 is a part of the body of a saxophone with my improved valve stopstructure in place.

Fig. 2 is a transverse detail sectional view showing the stop means inside elevation.

Fig. 3 is an enlarged detail of the stop and its pad.

Considering the numerals of reference, 1 s the body or branch of asaxophone or similar instrument. 2 is the tone hole socket. 3 is thevalve suitably pivoted and carried by the keys. l is the guard having across member 41 suitably secured in proximity to the tone hole socket. 5is the stop secured to the guard rod 4 and being provided with asuitable pad 51 disposed and arranged to contact with the back of thevalve where it contacts with the broad flat surface.

In the structure illustrated, the valve or stop is held normally openfor its work.

However, the stop is available for the opposite motion and to limit theopening when ac- ;iated by a key.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

The combination in a saxophone or similar instrument of a tone holesocket, a pivoted valve pad cup having a pad therein and having animperforate outer surface, a suitable guard rod over said valve pad cup,and a stop my hand.

ALFRED J. JOHNSON.
